Do It Right Now
If you are traveling but still were not able to commit a ride so you can be fetching once you reach France, you have to make reservations now and do not delay. If for example you will not be able to have one, you might get a hard time in transporting anything on hand. If you want, you can have it from the Bordeaux airport or on the nice airport perhaps. That will really depend on your stance because it might get you busted if you will tend to be serious well enough with it. Just take the best shot.
